unpackGetExponentUnbiased
public static int unpackGetExponentUnbiased(float d) Extract and unbias the exponent of the given packed
float
value.The exponent is encoded biased as a number in the range
[0, 255]
, with0
indicating that the number is subnormal and[1, 254]
denoting the actual exponent plusBIAS
. Infinite andNaN
values always have a biased exponent of255
.This function will therefore return:
-
0 -
iff the input is a subnormal number.BIAS
= -127 - An integer in the range
[1 -
iff the input is a normal number.BIAS
, 254 -BIAS
] = [-126, 127] -
255 -
iff the input isBIAS
= 128#POSITIVE_INFINITY
,#NEGATIVE_INFINITY
, orNaN
.
